↵aThe number of varicosities at the first imaging session.
↵bNumbers in these columns indicate the number of dynamic varicosities (left) and appeared/disappeared varicosities (in parentheses).
↵cPF structural plasticity was quantified three times (between sessions 2–3, 3–4, and 4–5) during the behavioral task, whereas only once before (between sessions 1–2) and after (between sessions 5–6) the task. Therefore, the total number of appeared/disappeared varicosities during the task (between sessions 2–5) was divided by 3 to obtain the average number of dynamic varicosities per single imaging interval for an appropriate comparison.
NA, Not applicable.
